I'm pretty new to Ubuntu. I installed Ubuntu Netbook Remix 10.10 and it works perfectly. I recently upgraded to 11.04 and now the internet is very slow; when browsing it would take quite a while to simply load a page. I tried switching browsers and it would still happen. I've changed back to UNR so the Internet is usable. Any ideas of what I should try? Thanks.

I think I finally found the solution to my problem, only just done it and so far my browser is back to normal, if it changes or deteriorates i will let you know though.

I identified my driver to be an RT3090 and then found this post: http://ubuntuforums.org/showthread.php?t=1749179 I followed it and blacklisted the suggested rt drivers and FINALLY i think it has worked! Browser is back to normal speed instead of taking forever to load!

Thanks very much for everyones help, i hope this works for someone else! Maybe now i can enjoy 11.04! :)

Hi, I also experienced a huge slowdown in Chrome / FF4. After reading this, I switched from my PCI ethernet card to my second (internal) and surf speed seems to be back to normal.

There are many factors that can impact your Internet performance. Your ISP's performance can vary. Comcast in Fresno can run slower and slower for a few weeks and then become fast again. I suggest you run http://speedtest.net or another performance site to establish the actual network performance. In my personal experience with Comcast all of my network slowdowns have been ISP related with one exception when my cable modem started to die. Your ISP should be able to test your modem from the network. This isn't to say that your problem can't be perhaps driver related but you can easily verify network operation to get a complete picture of what's going on.

Just ran a speed test as suggested results are here: speedtest.net/result/1282592331.png Not really sure what it means? But as i said, i'm not experiencing any slowness at all when using Ubuntu Netbook Remix, which is what i'm using now.

It sounds like Remix was using a different and a better driver for your wifi card. See if you can find out which driver and which version the 2 OS's are loading respectively.

You can try using lshw -C NETWORK and lsusb to find out this information. This should be at least enough to help you track this down. You could paste this here, or start a new more detailed questions that contains this information.

I had this problem upgrading from Maverick to Natty. In the end, I had to blacklist some drivers which forced the system to use a different driver.
